The ADA4800-KGD is voltage buffer integrated with an active The ADA4800-KGD is ideal for driving the input of the Analog load. The buffer is a low power, high speed, low noise, high slew Devices, Inc., 12-bit and 14-bit high resolution analog front ends rate, fast settling, fixed gain of 1 monolithic amplifier for charge- (AFE), such as the AD9928, the AD9990, the AD9920A, the coupled device (CCD) applications. For CCD applications, the AD9923A, and the AD9970 to AD9979 family. active load current source (IAL) can load the open source CCD The versatility of the ADA4800-KGD allows for seamless sensor outputs, and the buffer can drive the AFE load. The active interfacing with many CCD sensors from various manufacturers. current load can also be switched off to use the ADA4800-KGD as a unity-gain buffer. The buffer consumes only 20 mW of static The ADA4800-KGD operates at supply voltages as low as 4 V power. In applications where power savings is critical, the and up to 17 V. ADA4800-KGD features a power save mode that further reduces Additional application and technical information can be found the total current consumption. The bandwidth of the ADA4800- in the ADA4800 data sheet. KGD buffer is also fully adjustable through the IDRV pin. The buffer of the ADA4800-KGD employs a push-pull output stage architecture, providing drive current and maximum slew capability for both rising and falling signal transitions. At a 4.7 mA quiescent current setting, it provides 400 MHz, −3 dB bandwidth, which makes this buffer well suited for CCD sensors from machine vision to digital still camera applications.
